TO THE OPERATOR OF A DAEWOO EXCAVATOR
Unsafe use of the excavator could lead to serious injury or death. Operating procedures, maintenance and equipment practices or traveling or shipping methods that do not follow the safety guidelines on the following pages could cause serious, potentially fatal injuries or extensive damage to the machine or nearby property.
Please respect the importance of taking responsibility for your own safety, and that of other people who may be affected by your actions.
The safety information on the following pages is organized into the following sections
1. “General Safety Essentials” on page 5
2. “Location of Safety Labels” on page 5
3. “Summary of Safety Precautions for Lifting” on page 5
4. “Work-site Precautions” on page 6
5. “Operation” on page 9

7. “Maintenance” on page 17
8. “Shipping and Transportation” on page 20
GENERAL SAFETY ESSENTIALS
ACCESSORY APPLICATIONS
The excavator has been primarily designed for moving earth with a bucket. For use as a grapple or for other object handling, contact Daewoo for proper installation and application. Lifting-work applications (unless restricted or prohibited by local regulations) are permitted in approved lift configuration, to rated capacity only, with no side-loading. DO NOT use the machine for activities for which it was not intended. DO NOT use the bucket for lifting work, unless lift slings are used in the approved configuration. Use of an accessory hydraulic hammer (breaker), work in rough terrain, demolition applications or other hazardous operation may require installation of additional protective structures to safeguard the operator.
LIFTING CAPACITY RATING CONFIGURATION
Lifting capacity ratings that are printed at the end of this safety section are based on the machine being level, on a firm supporting surface, with hooks and slings attached in approved configuration. Loads must be balanced and supported evenly. Use taglines to keep the load steady if wind conditions and large surface area are a problem. Work crew hand signals, individual tasks and safe procedures should all be universally understood before the lift is made.
IMPORTANT
Before using the excavator to make lifts check municipal and regional regulations or statutes that could apply. Governing ordinances may require that all heavy lifting be done with single purpose equipment specifically designed for making lifts, or other local restrictions may apply. Making heavy lifts with a general purpose excavator that can be used for digging, loading, grading or other work may be expressly forbidden by a regional injunction or other legal prohibition. Always follow all of the other instructions, guidelines and restrictions for Safe Lifting in the Operation and Maintenance Manuals
LOCATION OF SAFETY LABELS
Location of safety labels (decals) can vary from unit to unit. Refer to appropriate Operation and Maintenance Manual, and parts manual for your unit. Always replace damaged or faded decals.
